The goal of the HopOn partner FZU is to contribute in tackling the limits of pertinent material properties of wafers and photonic devices based on epitaxial barium titanate thin films integrated on a silicon platform. To this end, we will use broadband dielectric measurements with emphasis on the phase-sensitive terahertz time-domain spectroscopy. The experiments will be supported by computational studies of lattice dynamics and domain walls in barium titanate using atomistic and phase field modelling. Such a comprehensive research strategy will allow bringing an important feedback to optimize the novel Phoenix technology. As a member of the consortium with forefront industrial and academic players in the field of photonics, FZU will expand its know-how on the knowledge transfer to industry, enlarge its network of collaborators and acquire experience for new participations in joint EC projects.
